Optimal conditions were developed for the synthesis of 11H-isoindolo[2,1-a] benzimidazol-11-one, 5H-isoindolo[2,1-a][3,1]benzoxazine-5,11(6aH)-dione, and 6,6a-dihydroisoindolo[2,1-a]quinazoline-5,11-dione derivatives in the reaction of substituted 2-formylbenzoic acids with o-phenylenediamine, anthranilic acid, and anthranilamide, respectively. The bifolded structure of 6,6a- dihydroisoindolo-[1,2-a]quinazoline-5,11-dione was verified and investigated.
